1. Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal conditions, the fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8-10%, so it touches human skin and makes people feel soft Without being stiff. If the humidity of the cotton cloth increases and the surrounding temperature is higher, all the moisture contained in the fiber will evaporate, so that the fabric can maintain a water balance and make people feel comfortable.
2. Moisture retention: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between the fibers, which is bad for heat and electricity. Conductor, therefore, pure cotton fiber textiles have good moisture retention, and the common school blouses of pure cotton weave make people feel warm.
3. Heat resistance: pure cotton fabric has good heat resistance. When the temperature is below 110℃, it will only cause the moisture on the fabric to evaporate, and will not damage the fiber. Therefore, the pure cotton fabric is good for the fabric at room temperature, wearing, washing, printing and dyeing. No effect, which improves the washability and durability of cotton fabrics.
4. Alkali resistance: cotton fiber has a high resistance to alkali. The cotton fiber will not be damaged in the alkali solution. This performance is conducive to the washing of pollution after consumption, disinfection and removal of impurities, and it can also be used for pure cotton. Textiles are dyed, printed and processed in various processes to produce more new varieties of cotton.
5. Hygiene: Cotton fiber is a natural fiber, its main component is cellulose, there are a small amount of waxy substance, nitrogenous substance and pectin. The pure cotton fabric has been tested and practiced in many ways, and the fabric has no irritation or negative effect in contact with the skin. It is beneficial and harmless to the human body when worn for a long time, and has good hygienic properties.
